Newly Enlightened
I just realized that I was using a "regular" battery in a new light of mine that requires a high drain battery. The battery was a Keep Power 14500 840 mAh, 3.7V, 3.11Wh. The light worked but would not remain in high/100% mode. At times, it would momentarily function at 100% and sometimes it would simply flash. After talking to the builder, he discovered the error of my ways and set me straight. I ordered the appropriate cells and am awaiting delivery.
This discovery led me to ask about my other lights which I am now trying to learn more about. This can be confusing though, as information varies from manufacturer to manufacturer.
For example, I have a PFlexPro triple that states in the specs to use a single high drain 18650 battery. OK, seems simple enough, but there are many different specs for "high drain" cells. My PFlexPro will draw up to 12A in turbo according to the website. Higher modes use over 5A, but the Olight cell says for "High Drain Devices" but lists Max discharge current at 4A.
I own 3 of these O-light cells which I use in my S2 Batons with the following specs;
Olight 18650 Lithium-Ion 3400mAh Battery
Let's contrast that with this new Obtronics High Drain cell.
3500mAh Protected 18650 Battery Li-ion 3.7V Rechargeable Orbtronic 10A Dual Protection (Panasonic-Sanyo inside), For High Performance Flashlights
Battery Specifications:
More about protection:
Does the Obtronic meet the requirements even though it is rated for a max of 10A?
I realize this is getting to be a long post, but I am new at this, and I really want to understand how this works.
THANKS!
